BINDER FOR LOOSE LEAF BOOKS Filed April 16. 1930 INYENTOR ank $641M A TORNEY Patented May 12, 1931 UNITED STATES VIILLIAM J. MORTON, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO THE MGBEE FECE BINDER COMPANY, 011 ATHENS, OIIIO, A. CORPORATION OF OHIO BINDER FOR LOOSE LEAF BOOKS Application filed April 16,

My invention relates to that class of books composed of records, etc., which an organization desires to preserve in bound form. In many cases it is not convenient for a company to keep a binding machine with the materials for binding the volumes, such as paste, cloth, backs, etc.

My invention has for its object, to provide a binding which can be used without any of the usual paraphernalia employed in such operation.

A further object is, to provide a back which is loose, and can readily be inserted after the volume is bound.

Another object is, to provide a back which will be available for books of varying thickness.

A concrete embodiment of my invention is illustrated in the accompanying drawings, which are to be considered as a part of this specification, in which- Fig. 1 is a perspective view of a bound volume, showing my device, the method of inserting the back being indicated in dotted lines;

Fig. 2 is a cross-sectional view of the same; and

Fig. 3 is a detail view of the back, in detached position.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, the binder comprises two covers 1 and 2. These covers are folded at substantially right angles at 3, then bent at an angle at 4, then formed parallel at 5. The inner portion 6 of the covers 1 and 2 is provided with a pairpf holes 7, which are adapted to secure binding posts 8, which pass through openings 9 punched in the leaves 10 which are to be bound into a volume.

' The holes 7 are so positioned as to leave a space 11 intermediate the edges, 12 of the leaves 10 and the point where the angle 4 joins the inner portion 6 of the covers 1 and 2. The loose back 14 fits the spaces 11 so that its edges 15 and 16 can be inserted in these spaces 11 and slid into position, as clearly indicated in Fig. 1. Since the back 14 is loose, it is easy to print thereon the title,- etc.,

before sliding the back 14 into position Should'the back 14 be too wide for the thickness of the book, all thatis necessary is to. cut oif enough from the edges 15 and 16 to bring the back 14 to'the width required.

The'book is assembled or bound in the following manner: The binding posts 8 are placed in position in the inner portion6 of the cover 1; the leaves 10 are then placed on the posts 8, which enter the holes 9; the ends of the posts 8 are passed through the holes 7 in the inner portion 6 of the cover 2, and riveted in place. Obviously, any of the numerous forms of binding posts may be used, many of which'do. not have to be riveted, thus saving an operation. The covers 1 and 2 are then folded as shown in Fig. 1, and the back 14 trimmed to the correct width, when it can be inserted in the spaces 11 and, slid into place. V

From the foregoin description it is obvious, to persons skilled in the art, that any desired number of loose records may be bound into a volume, which will present a neat appearance when completed, and which can be made up without any of the material required for the construction or binding of books in accordance with standard practice.

Having described my invention, what I regard as new, and desire to obtain by Letters Patent of the United States, is:

1. A binding for loose leaf books, comprising a pair of covers bent upon themselves to form inner portions thereon, there being a plurality of apertures in said inner portions, binding posts for said apertures, portions of said covers extending beyond the rear edges of the leaves to be bound and then towards each other, there being spaces between the rear edges of the leaves to be bound and the folded portions of said covers, and a back which slidably fits in said spaces.

2. The combination, with a number of leaves to be bound into a volume, of a pair of covers, means to secure said covers to said leaves, portions of said covers projecting be yond said leaves inwardly forming spaces between the rear edges of said leaves and said projecting portions, and a detachable back which fits said spaces.

3. The combination, with a number of leaves to be bound into a volume, of a pair of covers, means to secure said covers to said leaves, a detachable back, means on said 5 cover which slidably engage and retain said back, there being spaces between the rear. edges of said leaves and said means.

4. The combination, with a number of leaves to be bound into a volume, of a pair of covers, means to secure said coverst'o said leaves, a loose back, means on said covers spaced from the rear edges of said leaves which retain said back in said spaces.

5. The combination, with a number of leaves to be bound into a volume, of a pair of covers, means to secure said coversto said leaves, said covers being bent to form slots between the rear edges of said leaves and: the bent portion of said covers, and a loose back slidably mounted in said slots.

6; The combination, with a number of leavestobe bound into a volume, of a detachable back, a pair of covers which project beyond the rear edges of said leaves and form retaining means to hold said back between said covers, there being a plurality of open in in said covers, and binding posts mounte therein which extend through openings in said leaves to secure them to said covers. v

7. A loose leaf binder comprising a pair of covers, 'ortio'ns of which project beyond the rear e ges of the leaves to be bound and extend inwardly towards each other and are spaced from said rear edges, and a sliding back fitted to said space.
